personal protection

Many of us have taken steps to obtain a firearm, learn to use the gun, maybe even obtain the credentials to carry a gun for personal protection in the form of a concealed carry license. How many have taken any further training in the form of proper tactics for an armed confrontation? How many even practice regularly to become proficient with the gun they carry for protection? I venture to say that the number is relatively small in comparison to the number of concealed carry permits out there.
